As the number of data centers continues to increase in the United States, the good news is that they are becoming much more energy efficient. A new report from the Lawrence Berkeley National Laboratory has found that electricity consumption by data centers nationwide, after rising rapidly for more than a decade, started to plateau in 2010 and has remained steady since, at just under 2 percent of total U.S. electricity consumption.

Massive Trove of Battery and Molecule Data Released to Public

Kristin Persson - Materials Sciences Division

The Materials Project, a Google-like database of material properties aimed at accelerating innovation, has released an enormous trove of data to the public, giving scientists working on fuel cells, photovoltaics, thermoelectrics, and a host of other advanced materials a powerful tool to explore new research avenues. But it has become a particularly important resource for researchers working on batteries.

New Berkeley Lab Study Tallies Environmental and Public Health Benefits of Solar Power

Solar power could deliver $400 billion in environmental and public health benefits throughout the United States by 2050, according to a study from Berkeley Lab and National Renewable Energy Laboratory.

Modernizing a Technology From the Vacuum Tube Era To Generate Cheap Power

When scientists Daniel Riley and Jared Schwede left Stanford University last year to join Cyclotron Road, Lawrence Berkeley National Laboratory’s program for entrepreneurial researchers, their vision was to take thermionics, an all-but-forgotten technology, and develop it into a clean, compact, and efficient source of power.

Berkeley Lab Scientists Developing Paint-on Coating for Energy Efficient Windows

It’s estimated that 10 percent of all the energy used in buildings in the U.S. can be attributed to window performance, costing building owners about $50 billion annually, yet the high cost of replacing windows or retrofitting them with an energy efficient coating is a major deterrent. Berkeley Lab researchers are seeking to address this problem with creative chemistry—a polymer heat-reflective coating that can be painted on at one-tenth the cost.

Polar Vortices Observed in Ferroelectric

Berkeley Lab researchers have observed polar vortices in a ferroelectric material that appear to be the electrical cousins of magnetic skyrmions. This discovery holds intriguing possibilities for advanced electronic devices and could also rewrite our basic understanding of ferroelectrics.

Weaving a New Story for COFS and MOFs

An international collaboration led by Berkeley Lab scientists
has woven the first 3D covalent organic frameworks (COFs) from helical organic threads. The woven COFs display significant advantages in structural flexibility, resiliency and reversibility over previous COFs.

Researchers Pinpoint the Drivers for Low-Priced PV Systems in the United States

LowPriced PV cover

The price of solar photovoltaic (PV) systems installed on homes and small businesses spans a wide range, and researchers from Berkeley Lab have published a new study that reveals the key market and system drivers for low-priced PV systems.

Seeing the Big Picture in Photosynthetic Light Harvesting

Berkeley Lab scientists have created the first computational model that simulates the light-harvesting activity of thousands of antenna proteins that would interact in the chloroplast of an actual leaf. The results point the way to improving the yields of food and fuel crops, and developing artificial photosynthesis technologies for next generation solar energy systems.

One-Stop Shop for Biofuels
